Hello,
I have implemented Carlo's approach in my base page and wrapped methods
around it to create page parameters and redirect to the previous page. Thank
you for this contribution.
Everything works just fine, but there are some voices on my team that think
that this approach is unnecessary and overly verbose. Though, no
alternatives are presented.
Is this approach recommended by others on this list? Does anyone have a
pointer to a similar implementation in 1.4 (PageReference?). We are still on
1.3, but it would be interesting.
Thank you,
Kariem
